دانلود کتاب Specification for Zirconium and Zirconium-Alloy Welding Electrodes and Rods

This Specification prescribes the requirements for classification of zirconium and zirconium alloy electrodes and rods for GTA, GMA, and PA welding and will benefit welding professionals. AWS A5.24/A5.24M:2005 is a revision of the zirconium welding electrode document last revised in 1990. The compositions specified for each classification represent the latest state-of-the-art. Additional requirements are included for testing procedures, manufacture, sizes, lengths, and packaging. A guide is appended to the specification as a source of information concerning the classification system employed and the intended use of the zirconium alloy filler metal. This Specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.
